Versuchsvorschrift

In a separable flask equipped with a stirring rod, 0.080 mol (16.98 g) of DADMB, 0.010 mol (2.92 g) of APB-p and 0.010 mol (2.92 g) of APB-m were dissolved in 241 g of DMAc. With stirring 0.09 mol (19.63 g) of PMDA and 0.009 mol (2.65 g) of BPDA were added to the resulting solution to perform the polymerization, thereby obtaining a viscous, polyimide resin precursor solution (B).
